Just to help clear up some financial misconceptions a few people have, trading Flynn saved Seattle $5.25 million total cap space compared to keeping him for one more year ($3.25 million this year plus $2 million next year). We also got two draft picks, which IMO matters just as much as the money. And also, those savings will roll over into future seasons, so it's hardly a meaningless transaction. Far from it.
I'm more bullish on Flynn than many other trade supporters, but I still feel this is an acceptable risk with a good reward. Seattle badly needs to gain cap space for next season and they are always looking for ways to add future picks. The odds of actually needing Flynn to save our 2013 season are remote. And even if Flynn were to make a difference in 2013, who's to say his replacement might not be so capable? If we get Tyler Wilson in the 4th round for example, I'd consider the position upgraded.
